Answer:

It is more likely she draws 2 red cards

Step-by-step explanation:

Given that:

Number of red d cards in deck = 26

Number of face cards = 4 * 3 = 12 face cards

If two cards are drawn with replacement ;

Probability = (required outcome / Total possible outcomes)

P(1st card red) = 26 /52) = 1/2

P(2nd card red) = 26 /52 = 1/2

P(1st card red) * P(2nd card red)

1/2 * 1/2 = 1/4 = 0.25

P(1st card face card) = 12/52 = 3/13

P(2nd card, face card) = 12/52 = 3/13

P(1st card face card) * P(2nd card face card)

3/13 * 3 /13 = 9/169 = 0.053

0.25 > 0.053

It is more likely she draws 2 red cards

Answer:

$843.67

Step-by-step explanation:

1. Calculate the discount that was taken off from the original price.

$896 x 12% = $107.52

2. Subtract the discount taken off from the original price. This gives you the total paid AFTER the discount was taken.

$896-$107.52= $788.48

3. Calculate the tax amount by multiplying the discount price by the tax rate.

$788.48 x 7% = $55.19

4. Add the tax amount back to the discount price.

$788.48 + $55.19 = $843.67

Step-by-step explanation:

Given :

A shoe store buys a shipment of Nike shoes that cost $70 each to the purchases.

They want to markup their prices for the customers by 30%.

To Find :

How much would the customer pay for a pair of Nikes.

Solution :

C.P = $70 .

It is given that selling price is 30% more than the S.P.

So, S.P = C.P + C.P×0.30

S.P = C.P×1.30

S.P = 70×1.30

S.P = $91.

Therefore, the customer would pay $91 for a pair.

Answer: 56 785 is written as fifty six thousand, seven hundred and eight five. The number 406 090 is written as four hundred and six thousand and ninety. Numbers with seven, eight or nine digits, are millions. 46 758 442 is forty six million, seven hundred and fifty eight thousand, four hundred and forty two.

Step-by-step explanation:

The number would be 794 in figure form which represents seven hundred and ninety-four.

A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9. Based on the basic value of its digits, different types of number systems exist.

Calculating the number of quantities for an object or the Number of things left in the container are only two examples of the types of mathematical operations that utilize the Number System.

We have to write the number seven hundred and ninety-four in figures

As per the given statement, the expression would be:

⇒ 700 + 94

⇒ 794

Therefore, the number seven hundred and ninety-four in figure form would be 794.

Answer:

n = - [tex]\frac{4}{3}[/tex]

Step-by-step explanation:

Given

- 5(n - 1) = 7(n + 3) ← distribute parenthesis on both sides

- 5n + 5 = 7n + 21 ( subtract 7n from both sides )

- 12n + 5 = 21 ( subtract 5 from both sides )

- 12n = 16 ( divide both sides by - 12 )

n = [tex]\frac{16}{-12}[/tex] = - [tex]\frac{4}{3}[/tex]

Answer:

Step-by-step explanation:

To solve this you have to use the distributive property.

So first you would distribute the -5 to n and -1.

So the new equation will be -5n + 1 = 7 (n + 3)

Next, distribute the 7 to n and 3.

The new equation will be -5n + 1 = 7n + 21

Next you simplify by adding 5n to both sides which will give you 1 = 12n + 21

Then you subtract 21 from both sides and get -20 = 12n

So then you divide both sides by 12 to get n by itself and you are left with  -5/3 = n

==========================================================

Explanation:

This is a 45-45-90 right triangle. Any triangle of this form is isosceles, where the two legs are the same length. In this case, m and n are those two legs. So m = n.

We can then apply the Pythagorean theorem to say

a^2 + b^2 = c^2

m^2 + n^2 = (9*sqrt(2))^2

m^2 + m^2 = 9^2*(sqrt(2))^2

2m^2 = 81*2

m^2 = (81*2)/2

m^2 = 81

m = sqrt(81)

m = 9

As a shortcut, the hypotenuse of a 45-45-90 triangle is equal to sqrt(2) times the length of either leg. If m is the length of the leg, then m*sqrt(2) is the length of the hypotenuse. So in a sense, we take this thought process backwards to go from a hypotenuse 9*sqrt(2) to a leg length of 9.

Answer:  The question is The Gardener charged $0.50 per plant and a flat payment of $75. Which function represents this scenario?

The answer is 0.50x-75

The total cost will be the product of the gardener charged and the number of plants. The total cost is $ 37.5

It is also known as the product. If the object n is given to m times then we just simply multiply them.

The gardener charged $ 0.50 per plant and $75 to plant all of them.

Let X be the gardener charged and Y be the number of plants.

The total cost will be the product of the gardener charged and the number of plants. That can be written as

Total cost = X × Y

Total cost = 0.50 × 75

Total cost = $ 37.5

Step-by-step explanation:

Answer:

x = -0.4

Step-by-step explanation:

Given:

-9x + 0.4 = 4

To move all constant to the right side of the equation, perform subtraction operation

That is, subtract 0.4 from both sides of the equation

-9x + 0.4 - 0.4 = 4 - 0.4

-9x = 4 - 0.4

-9x = 3.6

Perform division operation to isolate the variable

That is, divide both sides by -9

-9x / -9 = 3.6 / -9

x = -0.4

Answer:

1 Subtract 0.4

2 Divide by -9 on both sides
